The chemicals you use for agriculture and horticulture are now controlled by the Hazardous Substances and New Organisms (HSNO) Act 1996, which replaces old laws such as the Pesticides Act 1979 and the Toxic Substances Act 1979.
As a vegetable grower or a contractor working in a commercial garden, these are some of the typical groups of chemicals that you might use.
- Fuels
- such as Petrol and Diesel
- Herbicides
- such as Roundup, Frontier, and Trophy
- Insecticides
- such as Confidor and Tamaron
- Fungicides
- such as Acrobat MZ 690 and Amistar WG
If you store fuels you may need a Location Test Certificate for your premises (previously a Dangerous Goods Licence), and/or a Tank Certificate for your bulk tanks.
You may need an Approved Handler Certificate for people handling the pesticides, although not all employees on the farm need to be Approved Handlers.
Location Test Certificates
You will need a Location Test Certificate:
- if you are using and/or storing particular chemicals above certain minimum quantities
- as a general rule, if you currently hold a Dangerous Goods Licence for your premises you will need a Location Test Certificate. There are exceptions eg for diesel.
Approved Handlers
An Approved Handler must make sure that certain chemicals are handled safely, that they do not harm people, nor damage the environment.
The table at the end of this brochure shows which chemicals commonly used will need an Approved Handler. Note that not all farmers or farm employees will have to be Approved Handlers, as long as they are working under the guidance of an Approved Handler. However, both aerial and ground spray contractors will need to be Approved Handlers for most chemicals.
For more information about obtaining an Approved Handler certificate, please refer to the Quick Guide - Approved Handlers
How to get Test Certificates
You must obtain your certificates from a Test Certifier. To find your nearest Test Certifier check the register or call ERMA New Zealand for a list of Test Certifiers to be posted to you.
Tracked chemicals
The most hazardous chemicals need tracking, and you will need an Approved Handler in order to use them. To buy them your supplier will need to confirm you are an Approved Handler, and that you have a Location Test Certificate if needed. The table at the end shows which chemicals are tracked.
When do I need to have all my certificates?
For fuels, if you need Location Test Certificates and/or Approved Handlers they will be needed following a timetable starting in October 2004. If you already hold a Dangerous Goods Licence, ERMA New Zealand will contact you to let you know what you have to do.
Key dates for pesticide Approved Handler requirements
1 January 2005
You will need to be an Approved Handler by this date
31 December 2006
You will be deemed to be an Approved Handler until 31 December 2006 if you have two years consecutive and recent experience using pesticides under the old regulations. You will not need to actually prove anything to achieve this status, but may subsequently be asked to do so by an enforcement officer
1 January 2007
You will need to become a full Approved Handler by this date, which will require you to demonstrate an understanding of the new HSNO legislation and your experience
At a glance
You may recognise some of the chemicals you use in this table. However there will be others that are not listed here. Go to a Test Certifier to find out what you need to do.

What must I do now?
Not all the chemicals you use may be listed in this leaflet, but please be aware that all agrichemicals are controlled by the HSNO Act. For guidelines about handling and storing fuels such as petrol and diesel please see Compliance Guide - Petrol and Diesel (Farms).
You should:
- check your chemicals
- identify and obtain Test Certificates for Approved Handlers and/or Locations
- contact a Test Certifier if you have any queries about what is required for a particular chemical.
